Expected Ptr<cv::UMat> for argument 'contour'

[jbarth-ubhd]

Did build a new singularity image from docker ocrd/all:maximum today, approx. 14:00 CEST.

using this image (with OCR-D): https://digi.ub.uni-heidelberg.de/diglitData/v/duerer1527--aa--deskew.png

and using this command: ocrd-eynollah-segment -P models default -I OCR-D-004 -O OCR-D-005 # ...004 contains png above

I'll get this error message:
